A life of abuse, rape and murder
His first brush with the law was at the age of 13 when he stole an offertory box from a Glasgow church.
The 12 months' probation he received for that petty crime, committed in 1959, did not,
however, jolt him into a life of good behaviour.Later that year, the youngest son of Angus and Mary Sinclair appeared at Glasgow Sheriff Court on a housebreaking charge, for which he was later admonished.
However, it was in 1961 that Sinclair's life of crime took a sinister new twist when he was found guilty of lewd and libidinous practices against an eight-year-old girl.
For that offence he was given three years' probation.
It was seven months into that probationary period that he murdered for the first time.
Catherine Reehill was just eight when Sinclair sexually assaulted and strangled her in his family home.
Pointedly, the judge Lord Mackintosh described Sinclair as "callous, cunning and wicked" and said that the perpetrator was so obsessed with sex that he was capable of taking a life to satisfy his lust.
There was nothing in Sinclair's unremarkable upbringing which might have hinted at what he would become.
He was brought up in the St George's Cross area of Glasgow and attended Lovell Street Primary, followed by St George's Junior Secondary School.
While in Edinburgh's Saughton Prison serving his sentence for Catherine's murder, he trained as a painter and decorator.
In 1970 he married trainee nurse Sarah McCulloch in Edinburgh and two years later they had a son Gary whom they brought up in Glasgow.
To all who knew him, Sinclair was apparently living a stable family life between 1970 and 1979.
However, the convicted killer was never too far from being on the wrong side of the law. In 1980 he had a short spell in prison for illegally possessing a .22 calibre revolver and ammunition.
Further police investigations found he had committed a string of indecent assaults and rapes against boys and girls aged between eight and 11.
His method was predatory - waiting in flats and closes before grabbing his victims at knifepoint.
In 1982 he pleaded guilty to 11 of 13 charges and was sentenced to life in prison.
